  • Slide device, mechanical seal, pump and auxiliary artificial heart system
    Patent number: 10010661
    Abstract: Provided is a slide device which includes a fixed-side slide member having an annular-shaped first slide surface, and a rotary-side slide member having an annular-shaped second slide surface, with the slide device being configured such that the first slide surface and the second slide surface are positioned opposite to each other, and an outer peripheral side of the fixed-side slide member and an outer peripheral side of the rotary-side slide member are brought into contact with a liquid containing a blood component, and a region where the first slide surface and the second slide surface face each other along the rotary-side slide member, the first slide surface and the second slide surface are brought into contact with each other on an outermost periphery of the opposite-facing region of the first and second slide surfaces.

  • Slide device, mechanical seal, rotary device, pump and auxiliary artificial heart system
    Patent number: 8568288
    Abstract: Provided is a slide device which can reduce a frictional force more than a conventional slide device when used in an aqueous liquid containing a blood component. In a slide device which includes: a fixed-side slide member having a slide surface; and a rotary-side slide member having a slide surface, the slide device being used in an aqueous liquid containing a blood component in a state where the slide surface of the fixed-side slide member and the slide surface of the rotary-side slide member face each other in an opposed manner, at least one of the fixed-side slide member and the rotary-side slide member is formed of a member which is made of a material which contains silicon and has hydrate of silicon oxide on the slide surface thereof.
